Mothers' Use of Regulatory Talk with Toddlers in Chile and the US: How Do Cultural Values and Children's Gender Affect Mothers' Regulatory Talk at 12 and 30 Months?

Studies have shown that Chilean and US infants differ in their levels of self-regulation. One of the mechanisms of early socializing is the use of language, particularly mental state language. The current study seeks to deepen our knowledge of the ways in which mental state language is related to socialization processes in early childhood, including the ways both culture and children's gender influence a mothers' use of mental state talk.

The Impact of Contextual, Maternal and Prenatal Factors on Receptive Language in a Chilean Longitudinal Birth Cohort.

A secondary analysis was conducted on longitudinal data collected from ELPI, a representative Chilean survey to model Chilean infant's receptive language using contextual, maternal and prenatal factors. The sample for the current study comprised children aged between 36 and 48 months (n = 3921). The sample was re-assessed when children were aged 60-72 months (n = 3100).

Mothers' competence profiles and their relation to language and socioemotional development in Chilean children at 12 and 30 months.

The study of early parental competences is relevant because such competences are related to children's development; however, most studies have considered competences using a variable-centered approach in which each parental competence is examined in isolation. This paper approaches these competences using a person-centered approach, generating profiles that combine different competences in Chilean mothers assessed when their children were aged 12 months and again at 30 months. The aim of this study was to generate and compare these profiles and to analyze the associations of these profiles with children's language and socioemotional skills.

Breastfeeding initiation and duration in Chile: understanding the social and health determinants.

Background: Given the support for the numerous benefits of breastfeeding, a better understanding of social and health determinants is necessary, particularly in under-researched populations. We examined determinants of breastfeeding initiation and duration using a national cohort of Chilean mothers.

Methods: Participants included 13 738 families enrolled in the Encuesta Longitudinal de la Primera Infancia cohort.

Breastfeeding and behavioural problems: Propensity score matching with a national cohort of infants in Chile.

Importance: Potential effects of breast feeding on children's behaviour remains an elusive debate given inherent methodological challenges. Propensity score matching affords benefits by ensuring greater equivalence on observable social and health determinants, helping to reduce bias between groups.

Objectives: We examined whether the duration of breast feeding had an impact on children's externalising and internalising behaviours.

Depression, anxiety and PTSD in sexually abused adolescents: Association with self-efficacy, coping and family support.

Sexual abuse has the potential to generate serious emotional consequences for its victims, but there is high variability in the symptoms reported by different victims. Therefore, it is necessary to ascertain the factors associated with the symptoms presented by sexual abuse victims. The aim of the study was to use a single model to evaluate the relationship between sexual abuse characteristics (frequency, violence, relation with the aggressor and physical commitment), cognitive and behavioral factors (self-efficacy, active coping and perceived family support) and internalizing symptoms (anxiety, depression and posttraumatic stress) in a group of sexually abused adolescents.

Socioemotional skills between 12 and 30 months of age on Chilean children: When do the competences of adults matter?

Due to the rapid growth in early socioemotional skills during the first three years of life, significant variations in socioemotional development begin early and increase with time. Family competences as sensitivity and mentalization, contribute to differences among children of the same age. This study examines whether the level of socioemotional skills is stable or changes between 12 and 30 months of age, and whether primary caregiver sensitivity and mentalization, as well as educational level, are associated with changes in the level of socioemotional skills.

Differences in infant temperament between Chile and the US.

Temperament refers to individual differences in reactivity and self-regulation and is influenced by genetic and experiential variation and maturation. Temperament reflects biologically based individual differences that emerge in early life and remain relatively stable thereafter. Given the growing interest in cultural variation in infant temperament, this study examined the temperament of 12-month-old children in Chile and the US.

Maternal stress and perceptions of self-efficacy in socioeconomically disadvantaged mothers: an explicative model.

Studies have demonstrated that maternal stress and perceptions of self-efficacy influence a mother's performance, affecting her ability to interact with her child and to understand and answer his needs. The purpose of this study was to evaluate maternal stress and the perception of self-efficacy in the mothers of infants who are cared for in child-care centers and belong to the poorest segment of the Chilean population. To this end, these aspects were studied in 121 low-income, high-social-risk mothers with children between the ages of 4 and 9 months.

[Phonological acquisition in preterm infants].

Introduction: The stock of phonemes used in the mother tongue is mostly acquired towards the end of the first year of life. Systematic exposure to speech begins, maintains and enhances the learning of native phonemes and lowers sensitivity to non-native ones. Speech deprival gives rise to serious problems in the infant's phonological development, yet little is known about the effects that premature exposure to speech can have on this learning.

Infant sign language program effects on synchronic mother-infant interactions.

The effects of an intentional infant sign language program on mother-infant interactions were studied. Design was quasi-experimental, longitudinal, descriptive and comparative. The sample was composed of 14 mother-infant dyads, with the infants being between 5 and 9 months at the beginning of the study.
